CULTTVAToR-snovnn STRUCTURE.

Application filed :rune 22, 1925. serial No 33,729.

Niththese and other objects in view, my

invention consists in the .construction, arrangement and combination of the various parts of my cultivator shovel structure, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustratedin the accompanying drawings, in which:

Figure 1 shows a perspective view of a cultivator shovel embodying my invention; and I Figure 2 shows a vertical, central, sectional view through the same taken on the line of Figure 1.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally i a. support adapted to be mounted on a cultivator and to have mounted on it the shank l11 and shovel 12, l

The support from its upper to its bottom. part with the lower portion thereof inclined downwardly and forwardly as illustrated.

The upper portion of the support 10 has fitted to it the shank 11 just' shank 11 is fastened to the support by means of rivets or the like 13. The lower part of the support has a. slot 14 therein.

The rear surface of the shovel 12 is fitted to the lower surface of the support 10. y

A straight bolt 15 is `extended through the shovel 12 at right angles thereto and has its head 16 countersunk in the forward surface of the shovel 12. l y The rear lower surface of the support 10 around the slot 14: is so arranged as to lie in a surface substantially at right angles to the bolt 15 when the latter is installed at right angles to the shovel 12.

1() has its front face concave *f referred to. The f Vhile the surfaces of the shovel 12 are f curved and the rear surface 17 of the support 10 just referred to is flat, they are arranged nearly parallel as possible. y

The bolt 15 has on its a nut 18, which bears against the surface 17 for locking the shovel 12 to the support 10. The shovel 12 is pro vided at its upper end with a notch 19fto snug' liy receive and tit the lower end "of the shank i l' In certain cultivating jobs, a lower shovel may be found desirable in which case, the l shovel 12 may loe lowered by loosening and *sliding the bolt 15 downward in the slot 14. The notch 19 engages the sides of the shank 11 so that even though the shovel 12 is adjusted to a lower position than that'illustrated, the notch still serves to prevent rotation of the shovel on the bolt 15. Y y

I This is a feature of considerable importance in my cultiva'tor shovel.

TES Panini'forrlclaf*v There has been some problem involved lin f locking the shovel to the support in a structure of this type in such manner that the shovel will not rock sidewise.

In the present device, it is to be noted that the shank is fastened to the support at substantially different poin in itsheight, and that the shovel is fastened tothe support by means of the bolt 15 and is also connected with the shank 11 at the lower end thereof by receiving such lower end in the notch 19.

This latter connection is 'such as to hold the shovel snugly and rigidly against any rotation on the bolt 15.A y

v By providing` the notch 19, it is seen that the shovel 12 projects a little higher than the ordinary shovel, which is a mattei' of advantage in the cultivating of certainA soils.

Some Vchanges maybe. made in the details of the construction and arrangement of' my improved -cultivator shovel without departing yfrom the real spirit and purpose of my invention, and it is my intention to cover by my claim, any such modification of structure or use of mechanical equivalents, which may be reasonablyv included within its scope.

I claim as my invention Sv()r vA cultivator shovel comprising a support Y said support, said sup-y v shovel engaging said lower portion and hava nut yon said bolt, the sides of Ysel-id Aslot in porthzwing a slot in its lower portion, a the shovel counting With said shank and in,

conjunction With said bolt serving to hold ing in its upper end a notch having` parallel the shovel rigidly in position With respect to 10 sides to receive the lower end of the shank said support even when the bottom of the and engagethe 'sdesfthere'o a` bolt extended notch is spa-ced from the bottom of the Shank. through the sfhoveland through seid slot and Des Moines, Iowa, April 25, 1925.
